Just as the heroic weapons of inferior films and interstellar fiction chose weapons first when they came to mind, they were all laser weapons that generate a beam of coherent electromagnetic radiation by stimulating atoms or molecules to excite photons, but the rate of technological improvements has been A bit outdated. Today's lasers are used industrially very often, and are involved in the printing of document files in home offices and in applications such as playing movies in a home theater. Not only that, it also appears in medical journals and military news, but for the rest of the time it's basically just being applied to being reduced to reading bar code applications, which is overkill. But the laser is still very interesting, Sushil Kumar of Lehigh University insists there are lots of potential innovations that we have just started on. With the support of the National Science Foundation (NSF), he is having a plan for exploring its applications. Kumar, an associate professor in electrical and computer engineering, pays particular attention to the relatively undeveloped spectral regions of those lasers in the electromagnetic spectrum, namely THz, or far-infrared frequencies. A researcher at the cutting edge of terahertz quantum cascade laser technology, he and his colleagues have released high-temperature environments and other important performance characteristics, and the results of their lasers have also become a new world record. His research goal is to develop equipment that opens up a wide range of possible applications such as biological, chemical sensing, spectroscopy, explosives, as well as detection of prohibited materials, detection of disease, quality control of drugs and even understanding of stellar stars in telemetry astronomy And galaxy formation, here are just a few examples. (These are pretty cool stuff that will impress you.) However, in addition to the known advantages, Kumar said, terahertz lasers have been fully utilized and explored; however, the limitations of high cost and functionality hindered the application of innovation in a variety of fields. However, Kumar believes he is expected to truly unlock the potential of terahertz laser technology; he recently received a grant from the National Science Foundation to target phase-locked ultra-narrow beam arrays for high-power terahertz lasers and to create terahertz Lasers produce greater light intensity than current devices and remove barriers for large-scale research commercial applications.
